There was, to be sure, in the Renaissance an uncanny and glittering reawakening of the classical ideal, of the noble mode of evaluating all things; Rome itself, oppressed by the new superimposed Judaized Rome that presented the aspect of an ecumenical synagogue and was called the "church," stirred like one awakened from seeming death: but Judea immediately triumphed again, thanks to that thoroughly plebeian ressentiment movement called the Reformation, and to that which was bound to arise from it, the restoration of the church—the restoration too of the ancient sepulchral repose of classical Rome.

的确，在文艺复兴时期，古典的理想、高贵的价值观念曾经历了光辉夺目的复苏。罗马就像一个假死苏醒的人一样在那座新建的犹太式罗马城的重压下面蠢动起来，那新罗马俨然是一座世界性的犹太教堂，它被称为"教会"。但是，很快地犹太教又一次获胜，这要归功于发生在德国和英国的运动，它被称为宗教改革，而实质上是平民的怨恨运动。伴随这场运动而来的是：教会的重振和古罗马再次被置于古老的墓穴安宁之中。

Furthermore, in the CTA rats, compared with water stimulability, FLI neurons of SON and DMV induced by sucrose stimulability had had much more expressions.6 When the same sucrose stimulability was given, FLI neurons expressions of SON, DMV and LH in the CTA rats were much lowwer than that in the control rats.Conclusions:1 CTA had an inhibitory effect on small intestine peristalsis, indicate taste preference has an effect on small intestine peristalsis, and inhibitory effect induced by CTA is corresponded with US, this effect may have relations with vagus efferent never and humoral regulation.2 In the electrophysiology experiment, discharges of vagus efferent never in the CTA rats are much more than that in the control rats, indicates taste and taste preference may regulate small intestine peristalsis via vagus nerve, and dicharge can continude 1 hour, indicate humoral regulation also exists in the regulation.

结论1建立味觉厌恶对小肠运动有抑制作用，提示味觉嗜好性对小肠运动有影响，而且味觉厌恶引起抑制作用是与条件刺激成对应关系的，味觉刺激引起的小肠蠕动的抑制作用可能与迷走神经传出神经及体液调节有关。2在电生理实验中，CTA大鼠迷走神经传出放电高于对照组的大鼠，提示味觉及味觉嗜好性可能是通过迷走神经对小肠运动进行调节的，放电至能持续60min，表明味觉及味觉对小肠运动的调节中还有体液调节的参与。

Firstly, the developing principles of the cylindrical internal helical gear are proposed through analyzing the movement and geometry requirements, which provides continuous contact between the mating gear surfaces. The tooth surface of the internal helical gear in the new gearing can be imagined as being generated by the normal section of the conjugated surface of the ball-tooth, moving along the radial projection of helix line of the tooth-root circle. Also, the proposed surface can be approximate tangent to the conjugated surface of the ball-tooth along a spacial curve.

因为混沌运动十分复杂，在研究和模拟混沌运动的过程中，不但要进行大量的数值计算，而且要将计算结果直观地展示出来以便观察混沌现象，完成这一任务非计算机不可。自从洛伦茨利用计算机发现了第一个混沌吸引子以后，30多年来正是有赖于计算机技术的发展，促使混沌的研究取得迅速的发展。另一方面，混沌运动是确定性系统中出现的一种貌似随机的现象，走向混沌有其独特的过程，只有展示出它的演化过程，才能很好地了解混沌运动。也就是说，混沌是一门关于过程、演化的科学而不是一门关于状态、存在的科学。因此，只有利用计算机才能将混沌的动态过程和演化的方式真正地体现出来。

Numerical simulations were done for a bistable latch valve of the system by FLUENT, and three groups of datum for different fluids were obtained with the same effective exit sectional area. Besides, a static mathematic model for the electromagnetic valve was established based on the obtained datum. Secondly, the motion of the valve spool was realized by UDF file in FLUENT. Three kinds of motions, uniform, acceleration and motion driven by the coupling effect of the liquid resistance and the electromagnetic force, were calculated and compared. The dynamic characteristic of the electromagnetic valve was obtained by analyzing the relationship of the mass flow rate of the inside flow field of the electromagnetic valve, the change of the drop pressure of the passageway of the valve, and motion time.
